NickelSearch (ASX:NIS) has reported significant sulphide intersections in its first diamond drilling at the Sexton Prospect in Western Australia.

The company believes the findings, which include a 9.85m interval with multiple sulphide intersections, confirms the presence of massive sulphide mineralisation at depth and increases confidence in the prospect's potential.

NickelSearch said the results from laboratory analyses are expected in around 5-6 weeks, after which it plans to drill two more diamond holes to further test the prospect's strike extent.

The company's share price closed up 20% today.
